Field Pressure change from AKS 32R to DST P110
Components & Tools Required:
- Personal safety equipment (Hand gloves and safety glasses)
Procedure
Work should be done by electric professionals only !
-
Disconnect power supply and ensure fan motor stop before removing side and front panel. Turn of isolator switch before servicing (Rotate Anticlockwise).
-
Remove service panel screw and open front panel and service panel.
-
Rotate Rotalock (receiver) valve spindel towards clockwise direction to close the valve. Pump down / remove Refrigerant from the system before servicing pressure sensor. (Keep liquid and suction line open.)
-
Remove the tie cable and wire from electrical box. Hold the connection pipe (Schrader valve) and rotate sensor anticlockwise to remove. Don’t damage connection pipe and thread.
-
Now assembly new spare in condensing unit. (Torque 15Nm)
- 075G1036(118U4021) – In Compressor discharge line.
- 075G1013(118U4025) – in Condensing unit Suction line.
-
After assembling pressure sensor, connect the cable from P110 sensor to Optyma controller as shown wiring diagram. Use give cables comes with spare part (See Annex -A for Wiring drawing).
-
Complete the electrical connection and ensure there is no leak observed and proper electrical connection.
-
Vaccum entire units, Danfoss recommend to fill fresh refrigerants and close the service and front panel.
